1 Claim.

My invention relates to devices for applying liquid Ito windshields. Itrelates particularly to .such devices for use with vehicles which areadapted to be driven at high speed by motors such as internal combustionengines. In this V tached to a vehicle already buil-t. Another ob-V:lect is to provide a device by means of which a suitable liquid such aswater may be delivered zo from a source of supply by gravity feedcontrolled by a valve in order that the operator may at any desired timecause the proper quantity of the liquid to be delivered in front of .thewindshield for cleaning purposes inxconjunction with the windshieldwiper.

, The novel features which I believe to be characteristic of myinvention are set forth with particularity 1n the appended claim. Theinvention itself, however, both r s to organization and meth# od ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specic embodimentswhen -read in connection with the accompanying drawings in which,

Fig. 1 is a perspective view showing .the front of a windshield havingthe device applied. Fig. 2 is a longitudinal sectional view showing oneform of the device applied to a windshield.

Fig. 3 is a transverse view on the line 3,-I of o F18. 2.

Fig. 4 is a view corresponding to Fig. 2 .and showing another form ofthe device.

Fig. 5 is a detail section view of a nozzle.

- Fig. 6 is a perspective view of another form of the invention.

Fig. 7 is a central section thereof. Fig. 8 is a detail view in sectionon the line '3 8 of Fig. 7. Referring to the drawings, the numerals 6and 3 designate the two halves of a windshield joined by a. middlereinforcing strip Ill and provided with wipers Il. The surrounding frameof the windshield is designated by the numeral I2. The roof or top ofthe vehicle is designated by the numeral I4.V

portions of the two windshield members 6 and 8.-

(Cl. ZIV-40.5)

The form of device shown in Figs. 2 and 3 which is adapted to be appliedto a vehicle afterit has been built will be first described. A containerI6 for holding cleaning liquidis secured within the vehicle in the`space underneath the 5 forward portion of the roof and located above thelevel of the windshield. The container I6 may be made of any sui-tableshape and material. Within .this container, two spaced sleeves I8 extendbetween the front and rear walls thereof. Rods l0 20 threaded at theirends pasathrough the sleeves i8 andare turned into the front of .thevehicle. Wing nuts 22 for the rear ends of the rods 20 are turned downupon the rear wall of the container. The container is provided with afilling opening 15 at its rear adapted `to be closed by a screw plug 24.A tube 26 externally threaded at its front and rear extends .through thereinforcing strip Ill and is secured in place by a 'front nut 28 and a.rear nut an. From the from end of the tube 2s, 2 branches 32 and 34extend in opposite directions horizont-ally and terminate in nozzles 36which are directed to spray liquid onto the upper front Theuquid. when1t, runs down the wlndshlem 25 members, a'cts in'conjunction with thewipers Il forncleaning purposes. It will be noted that the nozzles oropenings at the ends of the branches are in substantially verticalplanes with the axes 30 of the wipers.

The'threaded rear end of the tube 26 is connected'by a coupling member38 witha tubular projection 40 extending from a member 42 attached .tothe bottom of the container I6. The member 42 contains a bore inalinement with the passageway in the projection 40 and this bore isconnected by a passageway 44 with the interior. of the container I6. Therear end of the mem-A lber 42 lis provided with a packing gland 46 4othrough which a needle valve 484extends. This valve cooperates with avalve seat and has a head 46 by which it may be turned to shut off theow of liquid and may be turned in the' opposite direction to the desiredextent for controlling the vol- 45 This container has a filling neck 52extending up 55 2 through the root Il and closed by a screw plug 54.

` The delivery portion of the device extending from municationith thelower interior portion of the containerthrugh one or more ports 6-2. Themember B8 extends down through an opening in the roof H and has. itslower end portion threaded. A spacer 64 around the middle portion of themember 58 has its upper end in engagement with the lower side of theroof. A nut 6B cooperating with the threaded portion of the member 58engages the lower end of .the spacer 64 and serves' to securely hold thecontainer in place upon the roof. A tube 68 extends forwardly from thebore 60 below the ports 62 and has branches lll and 12 extending inopposite directions in front of the windshield. Nozzles 14 on theextremities of the branches serve to direct the liquid onto the upperportion of the windshield. 'I'he bore 63 just below the ports 62 isprovided with a valve seat with which a `needle valve 18 cooperates. Thestem of .this valve extends downwardly out of the bore 60 through apacking gland 80 andis provided with a head 82 Aby means of which thevalve may be operated into closed position and into the desired extentot open position. The container 56 is provided with -a filling openingadapted to be'closed by a screw plug 84.

Theoperation and advantages of my invention will be readily apparent inlconnection with the foregoing description and the accompanyingdrawings. Whenever the operator desires to clean-the windshield fromforeign matter, this may be quickly done without stopping the vehicle.All that he has to do is to open the needle valve the proper amount andstart the windshield wipers. Liquid will then flow by gravity from thecontainer and be deliveredthrough the nozzles upon the windshield forcooperative .action with the wipers. Furthermore when there is a mist orlight rain and operation of the wipers results is smearing thewindshield, delivery of the liquid from the container will quickly givea clear vision through the windshield. For use in freezing weather, theliquid may be oi' a non-freezing na ture with the result that frost isquickly removed from the windshield.

I claim:

A device for applying liquid to windshieids comprising a container forliquid, sleeves connecting two opposite walls of said container,threaded rods extending through said sleeves with one or their endssecured to the vehicle above the windshield, nuts on the other ends ofsaid rods for removably holding said container in place, a memberattached .to the bottom of said p container provided with a bore incommunication with the interior of said container, a vtube fordelivering liquid upon the windshield, a coupler for detachablyconnecting said tube with said bore containing member, a manuallyoperable valve in said bore containing member. said container havf
